Hi there!
I like the idea of simple conversions or repaints done by the collectors themselves. I think this would really personalize the collection and give it more worth to the owner. Sort of like repainting a house you just bought.
As far as value, these figures are fairly priced and a good candidate for reworking. Unless you are a very particular collector of goods as produced by the manufacturer it shouldn't impact the resale price too much if the job is well done.
We have had interesting conversations here about what impact there would be to a figure that was modified by me if I was the original sculptor. Would it be worth less, or possibly even more? I have several ACW figures lined up on the bench that are multiples in my collection and I plan on lopping off the heads and switching them around and then doing some repaints. I thought it might be fun to do some larger set ups to photograph, and with some figures I don't like to see multiples in the image.
Anyway I would love to see some conversions that collectors have made to their figures posted here on the forum... although I think I might re title it as something other than Pimping My Figure!
All the Best!
